Looking for dev shops

I was hoping to get some feedback from you mobile guys on something...

I run a backend development company. My goal is to develop a good relationship with some front-end mobile companies and help each other get clients and create great apps. Perhaps, even streamline restful apis or pub/sub frameworks for easier integration.

A lot of mobile dev companies I've come across end up hacking together an amateur rails or django app by themselves, but make a brilliant front end to use it. Either that, or they are given a company to work with that may not necessarily know how to deliver a good api for the mobile side.

My thought process was that everyone would only work on the side of the project they preferred, while gaining a more maintainable app.

We're about:

The iOS Network Lounge is one of the leading iPhone and iPad-related Meetup groups in San Francisco, for developers, designers, and curious minds.

The "Lounge" is an all-iOS-related community with regular events in San Francisco, designed to share knowledge, be inspired, and connect with other iPhone and iPad aficionados located in the Bay Area. Every event brings a speaker from the industry who presents new iPhone or iPad technology, latest innovation, monetization models, market trends, marketing opportunities, design tips, facts on mobile user behavior, and other topics related to iPhone and iPad apps. These events are open to developers as well as non-techies like designers, web/Flash developers, mobile project managers, VCs, research labs, journalists, etc.

The iOS Network Lounge is hosted and run by Marine Leroux, who heads mobile user experience at the media and information technology corporation Thomson Reuters. Previously, she founded and ran Bamboudesign, a UX consulting firm in France that expanded to iOS app development in San Francisco.
